Problems solved by technology

[0007] However, in the conventional revolving door using a glass surface material, glass that has been strengthened is used, but because it is glass, if a certain level or more of a strong impact is applied, fine cracks will occur, and there is a problem. cracked and damaged
In addition, since the load is concentrated around the hinge bearing parts, the surrounding resin cover may be damaged due to aging deterioration, environmental resistance, strength problems, cracks, heat cycles, etc.
Furthermore, when the opening and closing operation of the revolving door components (glass surface material or resin cover) is broken, there is a problem that the revolving door falls off from the main body.

Embodiment approach 1

[0033] figure 1 It is a perspective view of the whole refrigerator concerning Embodiment 1 of this invention, figure 2 It is the front view of the whole refrigerator concerning Embodiment 1 of this invention, image 3 yes figure 2 A magnified view around the upper hinge 2 of the Figure 4 yes figure 2 A magnified view around the lower hinge 3 of the .

[0034] In addition, in figure 2 Middle perspective shows the upper hinge 2 and a part around the lower hinge 3, in image 3 Middle perspective shows a part around the upper hinge 2, in Figure 4 A middle perspective shows a part around the lower hinge 3 .

[0035] Such as figure 1 as well as figure 2 As shown, the main body 1 constituting the refrigerator according to Embodiment 1 has an opening on the front surface, and is provided with revolving doors (the right revolving door 4 and the left revolving door 5) that can open and close the opening of the front surface. ). Additionally, if figure 2 As shown, the...

Embodiment approach 2

[0058] Figure 11 It is a perspective view of the second reinforcement 19 used in the refrigerator according to Embodiment 2 of the present invention.

[0059] Hereinafter, Embodiment 2 will be described, but overlapping descriptions with Embodiment 1 will be omitted, and the same reference numerals will be assigned to the same or equivalent parts as Embodiment 1. FIG.

[0060] The second reinforcement 19 according to the second embodiment is constituted by connecting the C-shaped member 19 a and the S-shaped member 19 b in the same manner as in the first embodiment, except for the hook portion 19 ba formed at the end of the S-shaped member 19 b in the longitudinal direction. In addition, the hook part 19bb is also provided in the short-side direction end part of the S-shaped member 19b, and the hole 19bc is formed in the center part of the hook part 19bb. Since the adhesiveness between the right cover 9 and the foamed urethane 17 increases by providing this hook part 19bb, i...

Embodiment approach 3

[0065] Hereinafter, Embodiment 3 will be described, but overlapping descriptions with Embodiment 1 will be omitted, and the same reference numerals will be assigned to the same or equivalent parts as Embodiment 1. FIG.

[0066] In Embodiment 3, a hard material such as a metal plate or a film having strength equal to or greater than that of the metal plate is pasted on the back surface of the tempered glass that is the outer surface material 13 of the revolving door. Thereby, even when the strengthened glass is broken, the metal plate or film is in contact with the U-shaped metal plate 16 and is hooked to the metal plate 16, thereby preventing the revolving door from falling off.

Abstract

The refrigerator is provided with a main body (1) having a front opening, a hinge provided on a side surface of the main body, and a revolving door which is supported by the hinge shaft and closes the front opening freely. Reinforced glass or resin that is the outer surface member (13); inner surface member (14) constituting the back; heat insulating material filled between the outer surface member and the inner surface member; installed on the four sides of the outer surface member and the inner surface member A frame-shaped cover made of resin; a metal reinforcing member for strengthening the side of the frame-shaped cover; a hinge bearing part (12) supported by a hinge shaft; and being installed on the upper side of the lower side of the frame-shaped cover and fixing the hinge bearing part The metal plate of the frame-shaped cover, the reinforcing member has an L shape, and a first hooking portion is formed at the end in the longitudinal direction of the short side, and the first hooking portion is arranged at a position overlapping the metal plate when viewed from the front, and when viewed from the side In the state of the overlapped position, one of the first hook portion and the metal plate is sandwiched by the other.

Description

technical field [0001] The present invention relates to a refrigerator, and more particularly to a fall-off prevention structure of a revolving door provided in a front opening and rotating about a hinge. Background technique [0002] In the revolving door installed in the front opening of the refrigerator, a thin steel plate such as a printed steel plate or a laminated steel plate is used as an outer surface material as a design surface of the door. Moreover, in the revolving door using such a steel plate surface material, it is formed in a structure in which a flat steel plate is formed into a substantially C-shape when viewed from the side, and a reinforcing plate made of steel plate (for example, Refer to Patent Document 1). [0003] And a hinge engagement part is formed in this reinforcement board, and this hinge engagement part is rotatably supported by the hinge provided in the main body of a refrigerator. [0004] In addition, in recent years, since designability i...
